Cal.com
Appointment scheduling for solo operators and teams. Main commercial codebase moved closed-source; public MIT repo cal.diy is strictly recommended for personal use while Cal.com Cloud Teams lists at $12/user/mo.
Pricing: Cal.com Cloud lists Individuals at $0/month (unlimited event types), Teams at $12/user/month billed yearly ($15 monthly), and Organizations at $28/user/month ($37 monthly, adding SAML SSO and SCIM). The public MIT repo cal.diy is free to self-host for personal, non-production use but omits Teams and SSO. Prices checked November 15, 2026.
Does it fit your team?
- Consider it if
- You want unlimited solo event types for $0/month, or a 2 to 45 person team needing round-robin and routing forms at $12/user/month on Cal.com Cloud instead of Calendly’s $16.
- Look elsewhere if
- You expect free MIT self-hosting to give your team production round-robin routing or SAML SSO: cal.diy is explicitly for personal, non-production use, and team features live in closed-source Cal.com plans.
- Can you use it commercially?
- MIT cal.diy is personal only; team features are closed
The public repository calcom/cal.diy carries an MIT License, allowing modification and deployment. However, its official README warns that cal.diy is “strictly recommended for personal, non-production use,” while commercial Teams, Organizations, Routing Forms, Workflows and SAML SSO sit in the closed-source Cal.com platform.
- Is it still maintained?
- Active
Last push on 2026-11-13. The repository is not archived.
- How hard is it to deploy?
- Moderate
Self-hosting cal.diy requires Node.js >=18, PostgreSQL >=13, Yarn (or Docker for local database), random NEXTAUTH_SECRET and CALENDSO_ENCRYPTION_KEY secrets, plus manual OAuth app credentials for Google/Microsoft calendars, Zoom and Stripe.
- What does it cost?
- Free solo Cloud plan; Teams $12/user/month billed annually
Self-hosting cal.diy has zero license fees beyond your Linux VPS and Postgres database. Cal.com Cloud pricing (checked November 15, 2026): Individuals $0/month (unlimited event types, multiple calendars, workflows, Stripe), Teams $12/user/month billed annually ($15 monthly), and Organizations $28/user/month billed annually ($37 monthly, adding SAML SSO and SCIM).
- What to watch out for
- Do not plan a production team rollout around self-hosted cal.diy
Many older guides assume self-hosting Cal.com unlocks free team scheduling. Today cal.diy omits multi-team routing, enterprise SSO and managed workflows, and the README explicitly advises using hosted Cal.com or licensed on-prem access for commercial workloads.
